Extend rustc -Zls #115735

This makes it show a lot more things and thus a lot more useful.

Related to https://github.com/bjorn3/rust_read_rlib which has been bitrotting for years. The exact subset of crate metadata contents I am printing partially overlaps with rust_read_rlib, but neither is a subset of the other. In the future everything rust_read_rlib could be added to rustc -Zls and a lot more can be shown. Example:

$ ./build/host/stage1/bin/rustc -Zls=all ./build/host/stage1/lib/rustlib/aarch64-unknown-linux-gnu/lib/liballoc-*.rlib
